Description:
 

Observation/sample depth below the sea surface. Units often reported as: meters, feet.

When used in a JGOFS/GLOBEC dataset the depth is a best estimate; usually but not always calculated from pressure; calculated either from CTD pressure using Fofonoff and Millard (1982; UNESCO Tech Paper #44) algorithm adjusted for 1980 equation of state for seawater (EOS80) or simply equivalent to nominal depth as recorded during sampling if CTD pressure was unavailable.

meters (m)

no
Description: 

Weighted mean depth of integrated seawater sample. This is calculated by taking a weighted mean of the various subsets of water that were available on the ship. For instance, if we collected 1L from 5m, 0.5L from 10m, the weighted average depth reflects the relative abundance of water from either depth.
